As soon as the words came out, Chen Kai was immediately stunned on the spot. For example, many eggs and turnips were placed in the gunpowder workshop, not only did he know about it, but he also asked the craftsmen to do it.

The proportion of black powder in the Ming Dynasty is different in various books, but among them, the proportion described in Qi Jiguang's "New Book of Ji Xiao" is actually no different from modern black powder. During Zheng Chenggong's expedition, Chen Kai was reading Qi Jiguang's books when he was idle, and there were too many things that could make him look shocking.

The problem of the proportion of gunpowder was solved by Qi Jiguang for Chen Kai. For the rest, if you want to further enhance its actual power, Chen Kai's thinking is two points, one is granularization, and the other is to improve the purity of raw materials. But these two things, unfortunately, with the level of science and technology in the last years of the Ming Dynasty, there is no need for him to take action personally.

The existence of granulated gunpowder in the Ming Dynasty is supported by unearthed cultural relics, but many Ming Dynasty civil officials and generals who used two knives did not understand it at all. But this problem does not exist in the Ordnance Bureau, at least the gunpowder craftsmen that Zheng Chenggong brought back from Quanzhou do not seem to be amateurs to that extent.

As for improving the purity of raw materials, charcoal, sulfur, and saltpeter, the Ming Dynasty people all have relevant technologies, even if they seem to be very unreliable, but the actual effect is very good. Even at the end of the Qing Dynasty, the power of the gunpowder purified in eastern Guangdong could be compared with the black powder of the West at the same time, so that even the Manchu court was so shocked that it could not help itself. At that time, the technology used was still the purification technology used in the Ming Dynasty!

In Chen Kai's Ordnance Bureau, sulfur is imported from all sources, so purification does not need to be carried out. In addition, charcoal is relatively simple, only saltpeter, since it has been self-produced, the purification process has to keep up, and the process used, among which requires radish and egg white to filter.

I remember that when those craftsmen first purified the nitrate accumulated from the pile, Chen Kai watched them add radishes and egg whites to it like cooking soup, and then constantly sifted out impurities, and the sweat began to bubble out. Among them, the chemical formula, how to achieve adsorption and transformation of impurities in eggs and radish, these Chen Kai felt that it was necessary to study it, but there was no leisure, but the actual effect was very good, the original soil nitrate can be white crystalline after purification, and Chen Kai had to sigh at the wisdom of Chinese workers.

Of course, the more important problem is that Chen Kai finally figured out the reason why those two guys looked at him so strangely this morning!

"Damn, I'm the king of big stomachs, I'm the king of big stomachs, I'm the king of big stomachs, and important things are said three times."

The reason for the rise in the price of eggs and radishes on Nanao Island is that Chen Kai's manure accumulation technology has begun to be practical and mass-produced, but the output of soil nitrate cannot be directly used in the manufacture of gunpowder, and needs to be purified, and purification requires a large number of radishes and eggs.

These ingredients, which are classified as raw materials in the account books, are separate from the accounts of the gunpowder manufacturing workshop. The people in the Ordnance Bureau don't know much about this matter, and there is no record in the account books there, plus Chen Kai's trip to Chaozhou, but it made him, the person in charge, almost direct and act in a black humorous absurd drama.

"You go ahead and don't worry about me."

Wiping his sweat, Chen Kai walked into the official room of the workshop. There is a bookkeeper here who is specially here, Chen Kai reviewed the account books, this batch of ingredients is indeed recorded, and the quantity has indeed reached the point that it can affect the price of Nanao Island.

lost face, but the problem was found, which made Chen Kai breathe a sigh of relief. It's a pity that this breath has just been relieved, but as soon as I returned to the small courtyard of the town house, I heard the cook muttering to her man, saying that she heard about the increase in grain prices when she was receiving vegetables at the house of the town town, and even felt glad that the turmoil of this grain price increase would not affect them who ate public grain.

"Yesterday it was eggs and turnips, and today it was grain, so I shouldn't have eaten it this time."

………………

The Ordnance Bureau's inspection officially ended the second day in Buda, and Chen Kai was indeed relieved that the workshops and gunpowder casting workshops in the city, as well as the nitrate accumulation factory, charcoal burning factory, and weapons test site outside the city, were able to operate normally according to his regulations.

In the next few days, Chen Kai focused on inspecting the other three towns on Nanao Island, except for Shenao Town, where Nanao City is located, to explore the specific situation and facilitate governance. The work didn't last long, because Nan'ao Island was so big, and he didn't plan to go down to the villages. However, with Zhu Yao's arrival, the visit to Longao Town had to end early.

"I have a reluctant request below, I implore Chen to join the army and tell us how you took Wang Shi to outwit Chaozhou City and kill Che Renzhong?"

It's not here to compete, Chen Kai is very fortunate and happy, especially this outwitting, which always makes him feel like a lupine scarf. Explaining, but talking lightly, Chen Kai didn't think he had done anything great, if he entered Liaoyang City in the Apocalypse Dynasty and killed Nurhachi, maybe he would blow it once or twice, a small car is heavy, it's really not a big deal.

However, this kind of thing is not so simple in the eyes of others, at least Zhu Yao admires Chen Kai's courage very much, especially when he sees that Chen Kai does not know any martial arts at all.

Regarding this matter, Chen Kai simply put forward a request to visit Haishan Island, and Zhu Yao welcomed it, and even took great pride in Chen Kai's visit to his hometown. But it's a pity that he can't be a tour guide, because he has met Chen Bao and is about to leave for Chaozhou to meet Zheng Chenggong and complete the official annexation to Zheng Chenggong's department.

"This person is a bit kind."

"Well, this person is indeed much more trustworthy than Huang Hairu, Xu Longna and others."

The next day, Zhu Yao set off for Chaozhou, and Chen Kai took the guide left by Zhu Yao and several officials and guards to Haishan Island. Here, it is only four nautical miles away from South Australia, and it is useless to reach here for half an hour.

On Haishan Island, some scenic spots such as the tomb of Song Xiang and Longfu Ancient Temple, Chen Kai really did not have the time and mind to visit, and the main task of his trip was to preliminarily survey the topography of Haishan Island and the production and life of the local people. During this period, he still stopped by when he went to Zhu Yao's lair to take a look, but it also caused the entourage and the local people to be puzzled, because although the historical events behind this tiger kicking stone are related to Zhu Yao, it is far from happening, and it is difficult for him to predict whether it will even happen.

After leaving Haishan Island, Chen Kai did not return directly, but rushed to Dongshan Island first for a turn before returning to Nanao Island. These two places, the overall situation made Chen Kai feel very speechless, the latter at least has a salt field to increase development efforts, but the former basically has nothing worth mentioning except for fishery, and even the 300 ports he has been longing for for a long time have not made him have too many illusions of bustling sea ships.

Fortunately, the islanders of Haishan Island have no resistance to joining Zheng Chenggong's department. However, if you want to use words such as the human heart, it is also a bit too exaggerated. They chose a way to continue to maintain a normal livelihood when Zheng Chenggong's department had the momentum of sweeping Chaohui, and that's it.

This is not because they don't care about the old owners of their homeland, the Ming court's harsh taxes and miscellaneous taxes are everywhere, they are also like many Chaozhou tyrants, they have already formed a village to resist taxes when the Ming court ruled this land, and it is only the government that has changed, not them. is like the famous sentence in Su Qi'er: "If you are really wise and martial, so that the country and the people are safe, who wants to be a beggar?" ”

If the Chinese people are not able to survive the good governance, few of them are willing to fight against the government. Since they have already chosen this path, Chen Kai will not be so optimistic that Zheng Chenggong will be able to easily conquer the hearts of Chaozhou if he wins the capital of Chaozhou. After all, this is not a real-time strategy game!

In charge of the civil affairs of Nanao and Dongshan Island, there will probably be a Haishan Island soon, but Chen Kai is not in a hurry, deep roots are the key, when he returns to Nanao Island, he will return to the small courtyard of the general town government as soon as possible to formulate relevant development plans according to the actual situation of these three places, especially the Ordnance Bureau. However, as soon as his front foot stepped on the threshold of the small courtyard, Chen Kai heard a soft female voice calling to him.

"Chen joins the army and is blessed, my young lady dares to love Chen to join the army and move to the garden to talk."
